Syrian rebels completed the withdrawal of heavy weapons from the frontline in Idlib on Monday, under the deal between Russia and Turkey to create a demilitarised zone, the state-owned Anadolu news agency said.

The Syrian state will recover Idlib through war or peaceful means, a minister was quoted as saying on Tuesday, pointing to the government's determination to defeat rebels there despite a Russian-Turkish deal that halted an expected army offensive.

Turkey will take action east of the Euphrates river in Syria and impose secure zones as it has done in the northwest of the country, President Tayyip Erdogan said in comments broadcast on Turkish media on Monday.
